As the Sand Fire has grown quite substantially in the past few days, it has become more difficult to track where it is going. I’ve found a couple of good links for up-to-date information on this fire. Map below courtesy of the Los Angeles County Fire Department.

In the 1930’s, Los Angeles County began construction of an additional roadway over the San Gabriel Mountains via the East Fork of the San Gabriel River. About half of the roadway, complete with with four larger bridges and a tunnel, was constructed. Work had progressed as far as “The Narrows” by 1938. However, the March 2-3, 1938 storms caused much of the roadway to be washed out. The project was then abandoned, leaving a large arch bridge stranded many miles upriver. The tunnel still exists as well, just north of the “Bridge to Nowhere”, though it has been sealed at both ends.

This is similar to what the removed bridges north of here would have looked like.1934 USGS Camp Bonita map showing the roadway completed to about 1 mile south of the “Bridge to Nowhere” site.1940 USGS Camp Bonita map showing the now stranded bridge location.

In the 1955, a new road building project commenced in the canyon. This new alignment would stay high above the canyon floor until it got nearer to the “Bridge to Nowhere”, allowing that earlier work to come to some use. Progress on this roadway was slow, mostly due to poor funding. Convict labor was used for most of the project, similar to many other road building efforts at the time in Los Angeles County. Two tunnels were constructed as well. These still exist and are mostly intact. This project too was cancelled in the late 1960’s, leaving another large scar in the canyon. This road is presently known as Shoemaker Canyon Road.

Today, the canyon is protected from future development through the Sheep Mountain Wilderness Area. Even without this protection, the geology of the canyon makes for a very expensive project. Maintenance would also be costly, as seen with State 39 through San Gabriel Canyon and above Crystal Lake. In time, all these structures and cuts will wash away, leaving the canyon with only bits of concrete and asphalt to show what was once here.

On my way home from a friends in Los Angeles on January 8, 2013, I decided to take the long way home. It was a beautiful day and I had plenty of daylight left. So, I took a turn into the mountains. It was the first time in a long time I had taken Hwy 39 – San Gabriel Canyon Road – and it was time to ride it on my motorcycle. I wanted to see where it was gated, it seems to change often how far up you can go. This time it was open through to Crystal Lake, which was good to see. I had a great time, even chatted with another motorcyclist at the gate for a while.

Once I headed back down the mountain, I headed over to the Glendora Ridge Road to meet the valley in Upland instead of Azusa. I wanted to see something different. Glendora Ridge Road is quite a lot of fun on a motorcycle, at some point I do want to bicycle it though. I saw quite a few cyclists (motor and pedal) that day, more people on two wheels than four. The snow on Mt San Antonio was a grand sight to see riding along the ridge. Winter in the San Gabriels is always a favorite of mine.

See you out there in the Cajon Pass on Saturday, August 12 at 8 am. While it will be warm, the tour should be a lot of fun. Make sure to bring water and good shoes to walk in. There will be more tours in the future, the next one will be in late September covering either US 99 from Los Angeles to Grapevine or US 80 from San Diego to Ocotillo.

Los Angeles County Department of Public Works has a wealth of information available on their website. With a bit of patience and some looking around, you can find quite a few treasures using their mapping application. I’ve so far found the original survey data for the “Bridge To Nowhere” roadway, plans for other roadways that were never built in the Sierra Pelona Mountains, as well as the forest service permit for the Shoemaker Canyon Road that was never completed.
